METHODS: From August 2006 to March 2008, the laparoscopic approach was used to perform CHIPC on 16 patients with malignant ascites induced by gastric cancer or postoperative intraperitoneal seeding. Each patient underwent CHIPC three times after laparoscopeassisted perfusion catheters placing. The first session was completed in operative room under general anesthesia, 5% glucose solution was selected as perfusion liquid, and 1500 mg 5 fluorouracil (5FU) and 200 mg oxaliplatin were added in the perfusion solution. The second andthird sessions were performed in intensive care unit, 0.9% sodium chloride solution was selected as perfusion liquid, and 1500 mg 5FU was added in the perfusion solution alone. CHIPC was performed for 90 min at a velocity of 450600 mL/min and an in flow temperature of 43 ± 0.2℃.RESULTS: The intraoperative course was uneventful in all cases, and the mean operative period for laparoscopeassisted perfusion catheters placing was 80 min for each case. No postoperative deaths or complications related to laparoscopeassisted CHIPC occurred in this study. Clinically complete remission of ascites and related symptoms were achieved in 14 patients, and partial remission was achieved in 2 patients. During the followup, 13 patients died 29 mo after CHIPC, with a median survival time of 5 mo. Two patients with partial remission suffered from port site seeding and tumor metastasis,and died 2 and 3 mo after treatment. Three patients who are still alive today survived 4, 6 and 7 mo, respectively. The Karnofsky marks of patients (5090) increased significantly (P < 0.01) and the general status improved after CHIPC. Thus satisfactory clinical efficacy has been achieved in these patients treated by laparoscopic CHIPC. CONCLUSION: Laparoscopeassisted CHIPC is a safe, feasible and effective procedure in the treatment of debilitating malignant ascites induced by unresectable gastric cancers.展开更多
